A drawer organizer for facilitating the location of an item stored in one of several drawers in one or more drawer organizer cabinets. Each drawer has an LED and a display device mounted on a front panel, as well as a CPU and a display device driver. The CPU memory contains the address of the associated drawer and communicates with an associated controller which receives drawer address and display information from a host computer. A user specifies an item to be retrieved from one of the cabinet drawers, the host computer transmits drawer identification signals to the controller, which converts these signals to a drawer address and supplies the drawer address to all drawer CPUs in the cabinet. If the incoming address matches the address stored in CPU memory of one of the drawers, this result is conveyed via the controller to the host computer, which then sends item display information to the controller. The controller forwards this information to the CPU, which relays this information to the display device driver and the information is displayed to the user. The CPU also activates the drawer LED.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A drawer organizer comprising: a cabinet having a structure for providing a plurality of drawer locations; a plurality of drawers each slidably mounted in a different one of said drawer locations between a closed position and an opened position, at least some of said plurality of drawers each having specific items assigned thereto, a front panel and a plurality of electronic drawer components including a display device mounted on said front panel for displaying information about items assigned to that drawer, a CPU for receiving drawer address signals from an associated controller, for comparing the received drawer address signals with a drawer address stored in said CPU, for sending a match signal to said associated controller when the received drawer address signals and the drawer address stored in said CPU match, and for receiving display information from said associated controller identifying the drawer contents, said display information being repeatedly transmitted by said associated controller at periodic time intervals, and for generating corresponding display information instruction signals, and a driver unit coupled to said CPU and said display device for converting said display information instruction signals from said CPU to display driver signals for said display device so that said display device displays information identifying the drawer contents so long as said display information is transmitted from said associated controller to said CPU; a pair of ohmic conductors for providing electrical connection between said plurality of electronic components in said at least some of said plurality of drawers and said associated controller; and a plurality of pairs of electrically conductive drawer slides each secured to a different one of said at least some of said plurality of drawers to provide an electrically conductive slidable drawer mount for the corresponding one of said at least some of said plurality of drawers, each one of said pair of electrically conductive drawer slides being electrically coupled to a different one of said pair of ohmic conductors and said plurality of electronic drawer components in the corresponding one of said at least some of said plurality of drawers.
A drawer organizer has a cabinet with multiple drawer slots. Each drawer slides in and out, and some drawers store specific items. Each of these drawers has a front panel with a display screen showing information about the drawer's contents. A CPU inside each drawer receives address signals from a central controller and compares them to its own stored address. If the addresses match, it sends a confirmation to the controller. The controller then sends display information about the drawer's contents to the drawer's CPU. The CPU instructs a driver unit to convert this information into signals for the display screen. The screen then shows the drawer's contents as long as the controller keeps sending display information. Electrical connections are made using ohmic conductors and electrically conductive drawer slides to connect the drawer's electronic components to the central controller.
2. The drawer organizer of claim 1 wherein all of said plurality of drawers have a front panel and a said plurality of electronic drawer components.
The drawer organizer is similar to the description above, except that in this version, *all* drawers in the cabinet have a front panel with a display screen and the associated electronic components (CPU, driver, etc.) described previously. So, every drawer is capable of displaying information about its contents.
3. The drawer organizer of claim 1 wherein said front panel has an electrically activatable visible indicator coupled to said CPU.
Building upon the addressable drawer organizer described previously, this version includes an electrically activated visible indicator, like a light, on the drawer's front panel. This indicator is connected to the drawer's CPU and signals the drawer's selection by lighting up when the drawer's address matches the signal from the controller. This indicator helps the user visually identify the correct drawer in addition to the information on the display screen.
4. The drawer organizer of claim 3 wherein said visible indicator comprises an LED.
The drawer organizer from the previous description that includes the electrically activated indicator on the front panel specifies that this indicator is an LED (light-emitting diode). So, when the drawer's CPU receives a matching address signal, it activates the LED, making it light up and visually indicating that it is the selected drawer.
5. The drawer organizer of claim 1 wherein said display device comprises a matrix display.
The addressable drawer organizer described earlier uses a specific type of display screen: a matrix display. Instead of a simple on/off indicator or a fixed set of characters, the display device shows content on a grid of pixels. The CPU controls each pixel, allowing flexible display of text or images representing drawer contents.
6. The drawer organizer of claim 5 wherein said matrix display comprises an organic light emitting diode display.
The drawer organizer with a matrix display from the previous description uses an organic light-emitting diode (OLED) display. OLED displays offer benefits like brighter images, higher contrast, and lower power consumption compared to traditional LCD or LED displays.
7. The drawer organizer of claim 1 wherein said at least some of said plurality of drawers each has a pair of opposing side walls; and wherein each of said plurality of pairs of electrically conductive drawer slides is secured to said opposing side walls of the corresponding one of said at least some of said plurality of drawers.
In the drawer organizer described previously, each drawer that has electronic components for addressability is constructed with a pair of opposing side walls. The electrically conductive drawer slides, which provide both physical support and electrical connectivity, are attached to these side walls. This secure attachment ensures stable sliding action and reliable electrical contact between the drawer's electronics and the central controller.
8. The drawer organizer of claim 1 wherein the number of said plurality of drawer locations is equal to the number of said plurality of drawers.
The drawer organizer has a cabinet with multiple drawer locations, and in this version, the number of drawers exactly matches the number of available drawer locations. This means that every slot in the cabinet is filled with a drawer.
